24:2=_:3=_:5.5=108:_=_:15
Answer:
24:2=36:3=66:5.5=108:9=180:15
Step-by-step explanation:
24:2=36:3=66:5.5=108:9=180:15
The complete statement is -
24 : 2 = 36 : 3 = 66 : 5.5 = 108 : 9 = 180 : 15
What is a expression? What is a mathematical equation? What are ratios?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Ratio is a quantitative relation between two amounts showing the number of times one value contains or is contained within the other.
We have the following statement -
24 : 2 = _ : 3 = _ : 5.5 = 108: _ = _ : 15
We have -
24 : 2 = x : 3 = y : 5.5 = 108 : z = k : 15
We can solve it partly -
24/2 = x/3
x = (24 x 3)/2
x = 36
Now, we have -
36/3 = y/5.5
(36 x 5.5)/3 = y
y = 12 x 5.5
y = 66
Moving further -
66/5.5 = 108/z
z = (108 x 5.5)/66
z = 9
Finally -
(108/9) = (k/15)
k = (108 x 15)/9
k = 12 x 15
k = 180
Therefore, the complete statement is -
24 : 2 = 36 : 3 = 66 : 5.5 = 108 : 9 = 180 : 15

Lalasa and yasmin are designing a triangular banner to hang in the school gymnasiums. They first draw the design on paper. The triangle has a base of 5 inches and a height of 7 inches. If 1 inch on the drawing is equivalent to 1.5 feet on the actual banner, what will the area of the actual banner be?
A. 17.5 ft2(squared)
B. 52.5 ft2
C. 39.375 ft2
D. 78.75 ft2
The correct answer is C. 39.375 square feet.
The student's question pertains to finding the area of the actual banner when a scale transformation is applied to a triangular design. To calculate the area of the actual banner, we need to scale the base and the height of the triangle from the drawing size to the actual size and then use the formula for the area of a triangle.
First, we convert the measurements of the base and the height from inches to feet using the given scale of 1 inch = 1.5 feet:
Base in feet: 5 inches × 1.5 feet/inch = 7.5 feetHeight in feet: 7 inches × 1.5 feet/inch = 10.5 feetWe then apply the area formula for a triangle which is Area = (base × height) / 2:
Area = (7.5 feet × 10.5 feet) / 2 = 39.375 square feet
Therefore, the correct answer is C. 39.375 square feet.
PLZ HELP ME FAST! Given that ∠MQL = 180° and ∠XQR = 180°, which equation could be used to solve problems involving the relationships between ∠MQR and ∠XQL?
A) (−5b + 115) = (125 − 10b)
B) (−5b + 115) + (125 − 10b) = 180
C) (−5b + 115) − (125 − 10b) = 180
D) (−5b + 115) − 180 = (125 − 10b)
Given
∠MQL=180°
∠XQR=180°
Hence ∠MQL=∠XQR
(We know that ∠MQL is the sum of ∠MQR and ∠RQL
and ∠XQR is the sum of ∠XQM and ∠MQR)
lets plug in these in our equation
∠MQL=∠XQR
∠MQR + ∠RQL = ∠XQM + ∠MQR
We can cancel out ∠MQR
hence ∠RQL = ∠XQM
hence we can infer that the opposite angles of intersecting lines are equal
similarly
∠MQR = ∠XQL
which is
125-10b = -5b+115
Hence the right option is A)

Greg drew a pair of parallel lines and a line segment next to each other on a chalkboard. Which of these statements best compares the pair of parallel lines and the line segment? (1 point) Parallel lines and the line segment have no dimensions of measurement. The parallel lines and the line segment always meet at a common endpoint which is called the vertex. Parallel lines and a line segment cannot lie on the same plane at the same time because they do not overlap. The parallel lines extend infinitely in both directions, and the line segment has two endpoints.
Answer: If drew drew a pair of lines and draw the segment between them, in a way that the segment is delimited by both lines, then:
If two lines are parallel, then they will never overlap each other, and if you draw a segment between them, then the segment will have two endpoints (one at each intersection with the lines)
So the correct answer is that the parallel lines extend infinitely in both directions, and the line segment has two endpoints.

Find the radius and the circumference to the nearest hundredth when d ≈ 3.8 in. Use 3.14 for π.
The radius is approximately 1.9 in and the circumference is approximately 11.94 in, both rounded to the nearest hundredth.
We have,
If we let d be the diameter of a circle, then the radius of the circle, r, is half of the diameter.
Therefore, we can find the radius of the circle by dividing the diameter by 2:
r = d/2
In this problem,
d ≈ 3.8 in, so we have:
r = 3.8/2 = 1.9 in
To find the circumference of the circle, we can use the formula:
C = 2πr
where π is approximately equal to 3.14 and r is the radius we just found. Substituting in the values, we get:
C = 2 x 3.14 x 1.9 ≈ 11.94 in
Therefore,
The radius is approximately 1.9 in and the circumference is approximately 11.94 in, both rounded to the nearest hundredth.

Which classification best describes the following system of equations?
12x+5y-3z=36
x-2y+4z=3
9x-10y+5z=27
inconsistent and dependent
consistent and dependent
consistent and independent
inconsistent and independent
Answer: These three planes are consistent and independent.
Explanation:
Since, if the system of planes has a solution then it is called Consistent, While, if it does not have any solution then it is called inconsistent.
Further, If the consistent system has infinite solution then it is dependent but if it has only a unique solution then it is called independent.
Here, given equations of planes are
12x+5y-3z=36 -------(1 )
x-2y+4z=3 -------(2)
9x-10y+5z=27 -------(3)
From equation (1), 3z=12x+5y-36⇒z=4x+5y/3-12 ------(4)
after putting this value in equation (2) and (3), we will get two equation in variables x and y
So, x-2y+4(4x+5y/3-12)=3 ⇒x-2y+16x+20y/3-48=3⇒3x-6y+48x+20y-144=9⇒51x+14y=153 --------(5)
And, 9x-10y+5(4x+5y/3-12)=27⇒ 9x-10y+20x+25y/3-60=27⇒ 27x-30y+60x+25y-180=81⇒87x-5y=261 --------(6)
after solving equation equation (5) and (6) we will get x=3 and y=0
substituting these values in equation (4) we will get z=0
Thus the solution of these three plane (1), (2) and (3) is x=3, y=0 and z=o
Which is the unique solution, Thus the given planes are consistent and independent.
The given system of equations is consistent and independent so, [tex]\fbox{\begin\\\ \bf option (3)\\\end{minispace}}[/tex] is correct.
Further explanation:
A system of equations is said to be a consistent system if the solution exists and if the solution does not exist then it is an inconsistent system.
If a consistent system has a unique solution then it is an independent system of equations but if the number of solutions is infinite then it is a dependent system of equations.

[tex]\left[\begin{array}{ccc}1&-2&4\\0&1&303\\0&0&491\end{array}\Biggm\vert\begin{array}{c}3\\0\\0\end{array}\right][/tex]
The equations obtained from the above augmented matrix are,
[tex]\begin{aligned}x-2y+4z&=3\\y+303z&=0\\491z&=0\end{aligned}[/tex]
The first equation is simplified to obtain the value of z as,
[tex]\begin{aligned}491z&=0\\z&=0\end{aligned}[/tex]
Substitute [tex]0[/tex] for [tex]z[/tex] in the equation [tex]y+303z=0[/tex] to obtain the value of [tex]y[/tex] as,
[tex]\begin{aligned}y+(303\cdot0)&=0\\y&=0\end{aligned}[/tex]
Now, substitute [tex]0[/tex] for [tex]z[/tex] and [tex]0[/tex] for [tex]y[/tex] in the equation [tex]x-2y+4z=3[/tex] to obtain the value of [tex]x[/tex] as,
[tex]\begin{aligned}x-(2\cdot0)+(4\cdot0)&=3\\x&=3\end{aligned}[/tex]
Therefore, the value of [tex]x[/tex] is [tex]3[/tex], the value of [tex]y[/tex] is [tex]0[/tex] and the value of [tex]z[/tex] is [tex]0[/tex] and the system has a unique solution.

Alexa buys 27 stamps, each stamp is of 1 square unit of area. She exchanges them for 8 sugar cubes, whose total volume is numerically (not dimensionally) equal to the total area of Alexa?s stamps. Which of the following represents the length of a cube of sugar
Alexa exchanges 27 stamps for 8 sugar cubes. To find the length of a sugar cube, we calculate the volume of each cube and then find the cube root of the total volume.
Explanation:In this scenario, Alexa buys 27 stamps, each with an area of 1 square unit. She exchanges them for 8 sugar cubes, whose total volume is equal to the total area of the stamps. To find the length of a single sugar cube, we need to calculate the volume of each sugar cube and then find the length of one side.
The total area of the stamps is 27 square units.Since each stamp has an area of 1 square unit, the total volume of the sugar cubes is also 27 cubic units.To find the length of a single sugar cube, we need to find the cube root of 27, which is approximately 3.Therefore, the length of a cube of sugar is approximately 3 units.
